A study by the U.S. Geological Survey (USGS) has found that PAHs from coal tar pavement sealers are the largest source of the cancer causing chemicals in 40 urban lakes recently studied. PAHs have been listed since 1987 as carcinogenic under California’s Proposition 65. The Safe Drinking Water and Toxic Enforcement Act of 1986, also known as Proposition 65, is intended to protect ...

Today, the IAQ Video Network and Cochrane & Associates announced the release of their latest educational video. Their newest production discusses polycyclic aromatic hydrocarbons and potential exposure risks. “PAHs are a group of chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic ...

The compendium will be used in the ongoing REACH-EN-FORCE 4 (REF-4) project which is coordinated by ECHA's Enforcement Forum. In this project, enforcement authorities in 29 European countries inspect restrictions of 14 substances which may be found in consumer products, such as textiles, toys or jewellery or used professionally, for glues or brazing fillers. The inspections under the REF-4 ...

Northeast Analytical, Inc. (NEA) is pleased to announce it will celebrate 20 years in business. April 2009 marks this milestone of NEA’s platinum anniversary. In April of 1989, a fledgling environmental laboratory was started at 301 Nott Street Schenectady as an incubator business and has grown into a world renowned specialty laboratory for trace Polychlorinated Biphenyl (PCB) analysis. NEA was ...

Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently ...

This method directly determines the concentrations of dissolved PAH concentrations in environmental sediment pore water samples. The method is important from an environmental regulatory perspective because it can achieve the analytical sensitivities to meet the goals of the USEPA narcosis model for protecting benthic organisms in PAH contaminated sediments. ...

Markes International (Llantrisant, UK) has released a new sorbent tube dedicated to the reliable analysis of polycyclic aromatic hydrocarbons (PAHs) in air. The new ‘PAH tube’ is the outcome of a detailed optimisation process for the analysis of these highly challenging analytes, which are subject to very low limit levels worldwide because of their carcinogenic ...

According to a new government report, commonly used pavement sealers containing cancer-causing substances are showing up in household dust. The report comes from research that was conducted in Austin, Texas by scientists from the U.S. Geological Survey (USGS).Sealcoats used on driveways, playgrounds and parking lots made with coal tar appear to be the major culprit. According to the USGS report, ...

BEIJING, China. – PerkinElmer Life and Analytical Sciences, a global leader in application-focused measurement and analysis solutions, today announced a new preconfigured system for the analysis of polycyclic aromatic hydrocarbons (PAH), organic pollutants widely distributed in the environment that can be carcinogenic at certain levels. The PAH Analyzer provides laboratories conducting High ...

Sitelab's fingerprinting procedure helps to identify the age or type of contamination on its clients' site at a fraction of the cost compared to conventional laboratory forensic testing. Field screening fingerprinting procedure Extract and prepare samples in solvent using Sitelab test kits; soil, sediment, water or oil (NAPL) samples can be analyzed. Test for GRO (BTEX): ...

Coal tar has been known to cause cancer since chimney sweeps in the 18th century were found to have high levels of scrotal cancer. It has also been implicated in contaminating waterways and stunting the growth, or killing, creatures that inhabit the water. Now, according to a new government report, the material is showing up in parking lot dust and entering homes. Coal tar is a commonly used ...

A new provisional analytical method co-developed by an ENSR toxicologist for assessing organic pollutants in sediments has been adopted by ASTM International (ASTM). The method measures the concentration of contaminants in sediment porewater - the water filling the spaces between grains of sediment - to which aquatic organisms become exposed. ENSR, part of AECOM, is a global environmental ...

A freshly sealed asphalt driveway or parking lot provides a deep black appearance that looks attractive to property owners and can help to extend the life of the asphalt. These pavement sealers are often made up of a mixture of sand, clay, polymers, water and either asphalt or coal tar. Pavement sealers that contain coal tar have come under increased scrutiny in recent years due to ...

CHROMATOTEC® is proud to support 2015 International Symposium on Polycyclic Aromatic Compounds conference, ISPAC 2015, to be held on September 13-17, 2015, at the "Cité Mondiale Convention Centre" in Bordeaux, France. ISPAC 2015 will bring together researchers worldwide and focus on the research of Polycyclic Aromatic Compounds (PACs) on multiple fronts of analytical ...

Anthias Consulting are working with charity RORO (Recycling Organisation for Research Opportunities), to connect redundant analytical instrumentation with academic institutions around the world that do not have the necessary finance to purchase new instrumentation. In September 2015, Diane Turner and Imran Janmohamed from Anthias worked with The Open University to send a Gas Chromatograph Flame ...

After analysis the Environmental Protection Agency, EPA, has released a draft toxicological review classifying benzo[a]pyrene, a combustion chemical in coal tar, as a human carcinogen. Additionally the chemical is harmful to developing organs and systems. Benzo[a]pyrene is not used commercially but is ubiquitous in the environment from forest fires, motor vehicle exhaust, ...

JRC-IRMM has released two new certified reference materials (CRMs), ERM-CZ100 and ERM-CZ120 which are targeted to control the measurements in the frame of quality control of ambient air in Europe. The monitoring of air quality is required by The European Air Quality Directives (2008/50/EC and 2004/107/EC). The two new CRMs have been developed to match requirements of these Directives. It relates ...
